The biggest problem is if you need to combine several furniture models and a human figure. In reality, a person is a flexible system, he takes different poses, his arms move, his elbows can adjust to the level of the table, his back can bend, his legs can take a comfortable position. The 3D model is stationary and it is often difficult to connect a 3D person, chair and table, for example. Something is necessarily a different size, it does not connect without overlapping or gaps. I took the model from the SH3D library. The girl sat well on a standard 47cm chair, everything matched. But the model's hands turned out to be at 71 cm, which is the level of the piano keyboard, which is 75 cm by 4 cm below the table level. Therefore, there are several possible solutions in such cases. 1. Change the size of one of these objects or even a person. It is undesirable to change the size of a person, there is a risk of getting a giant or a midget. So I decided to lower the table level to fit the model's arms. The correct 75 cm table height template is shown in red. It can be seen that the table level in the render is 4 cm lower. The second option is to increase the height of the chair seat by 4 cm. In this case, the girl's feet will not rest on the floor, it is unrealistic. The third option is the most difficult - to make a girl's figure from two halves, Legs and upper body with arms, from two parts of two models. The model allows you to make some parts of the body invisible. You can slightly increase the bottom and slightly decrease the top. Slightly increase the chair, slightly decrease the table. But then you can get a disproportionate figure from a girl. Therefore, it is better to lower the soulless table and leave the person alone. For realism, you should always think about the true proportions and decide where to change these proportions with minimal loss to the picture. If you don't think about anything at all and put everything together, it turns out to be funny, ridiculous and ugly nonsense. This is important in order to get closer to a professional result.
